Drive Test & Network Optimization
With a site on air, it is necessary to check the performance of the new site. This is done through verification drive tests. The sites are checked for validating integration parameters and ascertaining call performance: call termination, call origination, handover, power control RX Quality and RX Level etc.
Once a radio network is operational, its performance is monitored. The performance is compared against chosen key performance indicators (KPIs). After fine-tuning radio parameters, the results are applied to the network to achieve the desired performance. The main focus of radio network optimization is on areas such as power control, quality, handovers, subscriber traffic, and resource availability (and access) measurements.
